Ubuntu Kernel = vanilla kernel + a lot of patches (some backported others done by Ubuntu Kernel Team).
No differences but on Ubuntu kernel patches don't simply apply clean.
If you install linux-rt (already available in Lucid through Ubuntu archive) you install an Ubuntu kernel with PREEMPT_RT patchset applied. Instead if you install linux-realtime (available through my PPA) you install vanilla kernel with PREEMPT_RT patchset applied.
